l IMPROVEMENTIN Winn-WHEELS.

Specification forming part 0f Letters Patent No. 47,035), dated March2S. 1865.

` windmill- Fie. 2 a vertical section throu 'h the same in the line :umof Fig. l, and Fig. 3 a side elevation showing the position of theseveral parts ofthe windmill when the windwheel is pressed back andcheeked in its' movement.

. Similar letters indicatelike parts in each ofthe drawings.

My improvement` consists in a novel arrangement of friction-blocksimmediately b ehind the wind-wheel, against which the wheel is pressedby the wind wheny blowing' with violence, and which will then act asbrakes i to cheek and control the speed of its revolution; and, also, inthe combination of a lever and weight with the rear end of thewheelshaft, so as to counterbalance in a degree the pressure of the windagainst the wheel,

and determine the amount of force which shall suffice to press it backagainst the brakes.

The cost of manufacturing my self-regulating windmills is less than thatof the usual kinds, and its efficiency is not impaired by its automaticregulating capacity.

'lhe lwind-wheel A of my improved windmill is made of any desired size,and w'ith such finm and character of sails as may be most approved. Itis firmly secured upon the end of a shaft, B, Fig. 3, which is supportedin journal-boxes formed in the opposite ends of a box or frame,0,-pivoted upon the trame-work of a suitable tower, Y Y, so as t0 turnhorizontally in any direction with freedom and ease.. The bearings ofthe shaft are se extended as to allow the shaft to play or slidehorizontally in the journal-boxes to a considerable degree, the amountof play being-limited by collars or shoulders d d upon the shaft, asseen in Figs. 2 and 3.

A crank, b, is formed upon the shaft, midway between its bearin gs inthe box or frame C, to impart the necessary reciprocating movement tothe pump-rod D, attached thereto, as shown in Fig. 2.

The vane E, required to keep vthe wheel to the wind, is secured to theend of an arm, M,

extending rearwardly'in a right line with the wheel-shaft B- from theupper side of the'bearing-boX-G, to which it is rigidly attached, andthe rear end of the shaft B projects out from its journal-boximmediately below this supporting-arm M of the vane, as shown in Figs. 2and 3.

To obtain uniformitytin the revolution of the wind-Wheel A and shaft B,thus simply supported and adjusted, and to protect. the same fromViolent or sudden gales, which would drive them at too high a speed andinjure the machine, lplaee and secure a flat frictionringI or annularplate, G, of metal, (whose Adiameter is at least one-halt' that of thewindwheel,) against the arms ofthe wheel upon the inner side thereof atequal distances from' their axis, 4

Upon the front end of the bearing frame or box U, l secure firmly andrigidly four orI more radial arms, H H,Fig. 1, and upon the front faceof each extremity of these radial arms I so place friction-blocks K K,all of equal thickness, as that when the windwheel with its shaft ispushed back in its bearings the l friction-ring G will strike'and bearagainst these several blocks K K, as seen in Fig. 3.

As the shaft B is left free to slide or play, it is evident that withouta counterbalan'ce to the force of wind a breeze sufficient to turn thewheel would force it back against the blocks, arranged .as described,and prevent its 1novement. To resist the pressure of the wind,therefore, against the wheel, and regulate the amount .of -foree whichshall be permitted to turn it without cheek upon its speed, l pivot alever, 0, in a slot -formed in the arm M of the vane E, so that it shallswing vertically against the rear end of the shaft B, as shown in Figs.2 and 3. rllhe lower end of this leve-r plays between guides N N, whichproject rearwardly from the bottom ot' the box or frame C in a planecoincident with that of the arm M of the vane. A cord is attaehed'to thefree end of the lever, which passes thence over a pulley, S, pivotedbetween the guides N N at a point between the lever@ and box C, and

supports n Weight, P,secured to its lower end. This Weight is thus madeto counterbnhmce the force ot the Wind,.'for,' noting through the leverO upon the renr end of the shaft; B, it

carries und holds it forward, thuskeepinntho Wind-Wheel clear of thebrake-blocks K K, as W hen, however, the'pre'ssure seen in Fig. 2. ofthe wind pushing backward upon the shaft .is sov great as to exceed,that ofy ,the WeightI the wind wheelnnd vane, ninybepivoted'upon nnysuitable frmne-work.

Having thus ,fully described my invention.
